This book is so complete with jigs that are necessary to do the exact cutting required for good results that some woodworkers may not appreciate it. It has all the formulae to calculate the amount of lumber required for a project. If the woodworker has the patience to read this book and follow the design instruction, then experiment with different widths and numbers of the laminates, the possibilities are unending. Clarence Rannefeld, the author, has tried to introduce us to a whole new field in woodworking. Use your scientific calculator for the formulae, then cut and glue, and cut and glue some more and beauty will jump out at you. Above all, be patient. This type of woodworking is an art. Intarsia enthusiasts will love it.
